Executive Summary
The Kittitas County Road Safety Plan 2021 is a continuation of a biennial road safety plan program created to reduce
collisions within the County road network. Following the Washington State Department of Transportation’s (WSDOT)
Highway Safety Improvement Plan (HSIP) grant application methodology for creating a prioritized road safety plan,
crash data analysis in combination with staff identification of certain roadway characteristics throughout the County
road network, a list of prioritized projects implementing various countermeasures was created. These projects were
further prioritized with engineering judgement using considerations such as estimated project cost, feasibility, and
improvement timing. Total project costs were also determined and accumulated, and if needed, broken down in
phases to be completed as funding opportunity allows.
• Priority One – Intersection/Corridor Safety Improvements
No. 6 Road intersections at both Kittitas Hwy and Vantage Hwy are high frequency collision areas. Kittitas
Hwy and Vantage Hwy corridors and intersections were moved up in priority due to safety improvements
recently identified as deficient, out of date, or altogether missing throughout these corridors. Monitoring of
these corridors and intersections will continue to track the success of the recently constructed and future
countermeasures. Additional intersections have been noted countywide as needing safety implementation
or updates due to lack of countermeasures in response to accident activity.
ESTIMATED PROJECT COST - $336,600
• Priority Two - Bridge Rail-Code 3
60 bridges and/or structures with no rail or timber rail were classified as Code 3. Phases are identified by
maintenance districts. Some districts had less bridge rail to update and were then grouped with adjacent
maintenance districts. Phase breakdowns are provided in the project description with further cost estimates
by phase.
ESTIMATED PROJECT COST - $1,968,147 (Phases 1-3)
• Priority Three - Denmark Rd.
Denmark Rd MP 0.5 to MP 4.35 has moved up in scoring prioritization. It was noted in our previous 2017
and 2019 Road Safety Plans as priority five. This roadway has five bridges/structures that have deficient or
no bridge rail. The segment scoring 100 has a curve that needs safety improvements and contains accident
history. This project would provide safety countermeasures to the entire Denmark Rd corridor.
ESTIMATED PROJECT COST - $431,498
• Priority Four - Bridge Rail-Code 2
Bridges and/or structures with no approaches or non-crashworthy railing were classified as Code 2. Phases
are identified by maintenance districts. Some districts had less bridge rail to update and were then grouped
4
with adjacent maintenance districts. Phase breakdowns are provided in the project description with further
cost estimates by phase.
ESTIMATED PROJECT COST - $5,806,978 (Phases 1 -7)
• Priority Five - Bridge Rail-Code 1
Bridges and/or structures with rail that does not meet current AASHTO Manual for Assessing Safety
Hardware (MASH) standards were classified as Code 1. Following the phase identification process as in
Priority Two and Priority Four, phases are by maintenance district to create more manageable projects.
Phase breakdowns are provided in the project description with further cost estimates by phase.
ESTIMATED PROJECT COST - $2,060,284 (Phases 1-3)
• Priority Six - Huntzinger Rd.
Phases identified by milepost instead of total score because all phases are priority six. Milepost conscious
phases allow the county to continue heading south along the corridor. Phase breakdowns are provided in
the project description with further cost estimates by phase.
ESTIMATED PROJECT COST – $1,692,850
Introduction
The 2021 Kittitas County Road Safety Plan is a comprehensive program of safety improvements aimed at reducing
all collisions, but specifically fatalities and serious injury accidents across the entire county road network. This safety
improvement program was developed using a strategy similar to the Washington State Strategic Highway Safety
Plan: Target Zero 2019, in which crash data is analyzed to identify accident trends and contributing factors, and then
sites within the road system are prioritized using a risk-based ranking system. Safety improvement projects are then
developed to target specific locations and systemic improvements that provide the greatest benefit to the traveling
public by preventing potential fatal and serious injury accidents.
Due to the sporadic nature of crashes on rural county roads, it can be difficult to determine trends using past data
alone to choose locations for improvements. However, past crash data can be used to predict future crashes by
evaluating the contributing factors and targeting improvements for roads with similar characteristics. As a result,
Kittitas County has decided to utilize this strategy to allow for a proactive approach that benefits more locations
throughout the entire county road system and is more cost effective than only focusing on past crash locations.
Data Analysis
Data used for this evaluation was provided by Washington State Department of Transportation (WSDOT). The data
includes detailed information about crashes on Kittitas County roads from 2015 to 2019, including a comparison of
how Kittitas County’s roads to other public roads in the state, detailed in Table 1. Although overall, fatal and serious
injury collisions occur at a similar rate to other public roads within the state, Kittitas County is committed to reducing
these types of collisions and strives to collaboratively achieve the statewide goal of zero deaths and serious injuries
on Washington’s roadways by 2030. The Kittitas County Road Safety Plan focuses on identifying cost efficient safety
improvement projects that offer substantial safety benefits countywide and reduce potential fatal and serious injury
collisions along Kittitas County’s roadway network.

**Includes serious and non-serious collisions
The 2015 - 2019 WSDOT provided collision data was further evaluated to determine the predominant crash types,
contributing factors, and specific locations. As shown in Table 2 below, the predominant causes of fatal and serious
injury collisions in Kittitas County are “hitting a fixed object” and “overturning.” Crashes involving fixed-object hazards,
or non-traversable roadside slopes within clear zone accounted for 41.7% of all fatal and serious injury collisions.
Additionally, 25.0% of the fatal and serious injury collisions were caused by vehicles overturning. Unprotected
roadside slopes steeper than 3Horizontal:1Vertical are considered non-traversable and contribute to overturning
accidents. The predominant conditions where fatal and serious injury collisions occurred included higher speed
roadways with low lighting conditions, and where roadway curvature was a factor. This accident data seems
consistent for a county like Kittitas where most of the roadway network is rural without lighting features.
Accidents tend to be more severe when speeds are higher and where low light conditions hinder driver acuity,
especially in horizontal curves where drivers are more likely to leave the roadway. Non-intersection related collisions
accounted for 79.2% of the fatal and serious injury collisions, although a large proportion of total accidents (non-
injury, serious injury, and fatal) occurred at intersections and main corridors leading to potential for more serious
accidents at these locations. For the fatal and serious injury collisions accident report details please see Appendix A.

Risk-Based Prioritization Methodology
Run-off the road crashes have been identified as the predominant collision type in Kittitas County and are occurring
at a disproportionately high rate on specific corridors as compared to other public roads in the state as shown in the
crash data provided by WSDOT for 2015-2019, reflected in Table 2. As a result, this plan will focus on roadside
safety improvements to reduce the severity and number of accidents on Kittitas County roads where it is most likely
that run-off the road crashes will occur.
From a safety perspective, the ideal roadway is straight with roadsides that are flat and unobstructed by hazards.
Straight roadways eliminate the need for drivers to navigate curves, reducing the chances of running off the road.
8
Providing the recommended clear zone and roadside slopes allows drivers to safely recover control of a vehicle in
the event they do leave the roadway and helps ensure fixed-object hazards do not cause fatal or serious injury
accidents. The aforementioned roadway geometry and clear recovery area is the goal in improving roadside safety
but is often cost prohibitive due to the geography of the area and is not supported by rural character or practical
design. In cases where it is cost prohibitive to eliminate roadway curvature and create an unobstructed traversable
roadside, alternative improvements that may reduce the severity of an accident or alert a driver to a hazard should be
considered. This safety plan focuses on roadway segments and intersections where low-cost high benefit
countermeasures and improvements can be implemented. These countermeasures and improvements may include
improved or increased pavement markings, breakaway features on posts, guardrail deployment, bridge rail retrofits,
rumble strip installation, and signing and traffic delineation upgrades, all of which may be implemented to reduce fatal
and serious injury collisions.
Based on the crash data for 2015-2019, 76.2% percent of the total crashes involved roads with an average daily
traffic (ADT) of 175 or more and with a speed limit of 35mph of higher. In order to have the greatest potential impact
in reducing collisions, the county considered roads for evaluation and prioritization of safety improvements with the
following characteristics:
MINIMUM CRITERIA FOR INCLUDING ROAD SEGMENTS IN SAFETY PLAN:
• Paved: Asphalt Concrete Overlay (ACP), Hot Mix Asphalt (HMA), or Bituminous Surface Treatment
(BST).
• ADT of 175 or more.
• Posted speeds of 35 mph or more.
• Collision within segment in the past five years.
The minimum criteria include the preliminary eligibility requirements as defined by the U.S. Department of
Transportation Federal Highway Administration’s Highway (FHWA) Safety Improvement Program (HSIP) as stated
under the 2021 County Safety Program: Call for Projects solicitation for grant funding. Additional scoring criteria has
been developed by Kittitas County Public Works Staff and used consistently throughout multiple years of safety
planning to provide scoring and prioritization continuity. The additional criteria include a heavier weighted score for
segments listed in the previous County safety plan, inadequate clear zones with embankments or ditches, fixed
objects in the clear zones, roadway curvature – horizontal curve, and collision seriousness (injury, serious, or fatal).
County road segments possessing the minimum criteria characteristics, as well as the additional criteria
characteristics, were evaluated and scored by the weighted method shown in Table 3. The complete list of resulting
road segment prioritization is shown in Appendix B.

Development of Road Segment Safety Improvements
After roadway segments were prioritized using the risk-based scoring as described above, the results were reviewed,
and the list was shortened so the plan could focus on the segments that would see the most benefit from safety
improvements and eliminated erroneous results or locations reflecting outdated information.
Road segments with a score lower than 55 were removed from consideration in an attempt to break segments down
into higher priority rating and lower priority rating groups. Road segments that were within the scope of current
improvement projects or recently completed improvement projects were also removed. Each accident report was
examined for further details regarding the incident to further identify contributing factors, driver actions, alcohol or
drug influence, intersection related, and any countermeasures already in place. The list of candidate locations was
further reduced by eliminating roadway segments where accidents were alcohol or drug related with no hazard at the
site and segments where countermeasures were already in place and or where no countermeasures would have
prevented the accident. While these road segments are important to monitor, focus is given to other locations where
collisions due to deficiencies in the road structure can be addressed. The remaining roadway segments were then
evaluated for potential safety improvements and countermeasures.
10
Corridor and intersection improvements were identified as a safety need in this plan. Crash data shows a significant
number of total collisions, injury collisions (serious and non-serious), and fatal collisions along two of Kittitas County’s
major roads, Kittitas Highway and Vantage Highway. These two corridors, or highways, are high ADT, arterial
collector roadways in good condition providing local resident access and freight connections. Intersections along
these highways have been identified as areas where safety improvements would make a large impact to reducing
total accidents. Proposed updated and enhanced signage along these corridors and intersections would provide a
cost-effective safety countermeasure covering a relatively large County footprint.
Additionally, the County has recognized copious amounts of inadequate bridge railing. There is a total of 269 bridge
structures within Kittitas County, many of which have insufficient existing railing or no railing at all. Since these
observed hazards have a high potential for serious injury or fatal accidents, Kittitas County has chosen a proactive
approach to include these locations in this road safety plan to prevent potential future crashes. This preventative,
systemic, risk-based approach is supported using the Federal Highway Administration (FHWA) Systematic Safety
Project Selection Tool criteria, which states that a site can be identified as a candidate for safety investment if it has
multiple risk factors but no crash history.
Finally, Kittitas County previously recognized a need to collect data to support a clear zone inventory for the entire
County road system. Future safety improvement projects will be better identified using a more thorough clear zone
inventory targeting known hazard locations. For this reason, a planning project has been identified and will be
implemented as part of this overall safety plan to collect clear zone inventory data, which will create a roadside
hazard database, and identify potential locations and countermeasures for future road safety plans.
Prioritized Cost-Effective Safety Improvement Projects
Road segment safety improvement identification used a combination of spot location and systematic approaches.
After improvements were identified, they were prioritized based on the potential for crash prevention and greatest
benefit, as supported by engineering judgement.
Kittitas County evaluated the scoring and road segment safety improvement results to find high risk, sizable benefit
countermeasures to group together as countywide safety projects that promptly provide the biggest benefit for the
most efficient cost. By focusing on similarities in the roads and their needs, safety improvement projects were formed
rather than road focused projects, allowing the county to better reduce the possibility of fatalities and/or serious
injuries. Locations with similar geographic vicinity, or projects with similarly proposed improvements were grouped
together to provide efficient contracting and cost effectiveness. A summary of the Safety Improvement Projects can
be found in Table 4, followed by project details including preliminary scope, locations of the proposed work, and an
estimated cost for the improvements. Notes regarding the engineering judgment that affected project prioritization
can be found in the Executive Summary.

Priority 1: Corridor and Intersection Safety Improvements
This project provides corridor and intersection countermeasures and improvements at unsignalized intersections and
road segments identified as having insufficient, “out of date”, or non-effective safety measures based on accident
data analysis and safety studies. Both Vantage Highway and Kittitas Highway are 50 mph, high-ADT, arterial access
corridors with overall roadways that are in good condition which have a higher collision rate than any other County
road.(Appendix A, Table 2).This project would provide identification and target specific intersections as well as
potential spot-improvements to these heavily traveled intersections throughout the county with implementation of
countermeasures presumed to be effective for each specific location. Kittitas County recognizes that improvements
to these corridors may provide benefit to a great number of local residents, recreational travelers, and freight transit;
and, any improvements that could reduce potential future crashes are beneficial. We previously identified No. 6 Rd.
and Vantage Hwy, as well as two other intersections along Kittitas Hwy at Matthews Rd and No. 6 Rd, for safety
improvements. Emphasis should be put on corridor and intersection improvements on Kittitas Hwy and Vantage Hwy
as a combined 26% of all serious and fatal crashes have occurred on Kittitas Hwy and Vantage Hwy combined.
Additionally, all serious and fatal accidents at Kittitas Hwy and No. 6 Rd have occurred during dark hours with
yielding issues as the cause.
The combination of repeated accident history and their quantities at No. 6 Rd and Kittitas Hwy makes this
intersection a high frequency collision area (two reportable crashes per year over a three year period, or three or
more over a five year period) bringing this segment up in the priority list of projects. The Kittitas Hwy/No. 6 Rd project
would include providing an adequate clear zone, LED-enhanced signs, and possible increased visibility measures.
Continued monitoring and further evaluation will also continue at this location to identify potential future safety
improvement opportunities.
Local safety improvements along Kittitas Hwy and Vantage Hwy include large scale improvements such as widening
and bridge replacements with updated guardrail. The county is taking this opportunity to evaluate the
countermeasures recently installed for performance success to analyze if corridor related accidents decrease. This
will allow for identification of whether additional countermeasures may need to be implemented in the future.
Signage proposed includes, but may not be limited to, solar powered LED-enhanced flashing stop signs, LED-
enhanced stop ahead signs, LED-enhanced cross traffic signs, and additional warning signs such as “Cross Traffic
Does Not Stop” and “T intersection” in locations where accident frequency is high or the County has recognized a
need to increase safety. These areas include intersections or road segments where signage is not existing (but
should be), is lacking, and/or needs updated equipment. One example would be the intersection of Thrall Rd. and
Clemons Rd. (T-intersection) which has an existing outdated beacon light which is hard powered in. Additional
13
signage could include standard curve signs where not existent or LED-enhanced curve signs where accidents are
frequent or serious or fatal on curves such as Upper Peoh Point Rd (Appendix A, Table 1) which has multiple road
segments with high scores based on criteria rating in Appendix B, Table 1. Below is a figure depicting our current
intersection signage at rural intersections (left) and an intersection after the proposed signage improvements are
implemented (right).
Figure 1. Depiction of current County rural intersection (left) and a proposed County rural intersection with improvements (right).

Data shows LED-embedded flashing stop signs are proven to make unsignalized intersections safer, especially in
rural areas with low lighting. In a study published by the Minnesota Department of Transportation (Davis, G.A. 2014),
researchers found a 41.5% reduction in right-angle crashes after installing flashing LED-enhanced stop signs
throughout the state. Another study completed in Texas noted that the introduction of an LED-embedded stop sign
produced a 28.9% reduction in the number of vehicles not fulling stopping (Gates et. al. 2004), and a 52.9%
reduction in the number of vehicles moving through the intersection without significantly slowing down. A similar
yielding result was found in Virginia, where researchers also noted even higher compliance during dark hours (Arnold
and Lantz 2007). LED-embedded flashing traffic signs are also an efficient means of safety compensation for color
deficient or colorblind roadway users, especially during seasonal and light/dark time changes when sign colors and
shades can blend with the natural environment (Chandler, B. 2021).

Priority 1: Intersection/Corridor Improvements
ESTIMATED COST $336,600
• Vantage Hwy and Kittitas Hwy have had safety improvements recently constructed in previous projects. The
county would like to observe the recent improvements in combination with enacting future safety projects.
• The two intersections that will be the focus of this monitoring project are at Kittitas Highway and at No. 6 Rd
at MP 2.36 and No. 6 Rd at Vantage
Highway.
• No. 6 Rd intersections at both Vantage
Hwy and Kittitas Hwy may benefit from
intersection specific countermeasures.
Continued monitoring and evaluation
efforts at these locations will provide
future potential safety improvement data.

Priority 2: Bridge Rail Improvements – Code 3
Phase 1-County Maintenance Districts A - F
• 19 bridges or structures
Phase 2- County Maintenance Districts G - I
• 21 bridges or structures
Phase 3- County Maintenance Districts J - L
• 20 bridges or structures
Due to the large number of locations needing improvements, it would be cost prohibitive to provide improvements for
all locations in a single project. As a result, countywide bridge rail improvements will be executed in a series of
projects. Each phase priority will include a number of locations that are grouped by County Maintenance Districts (A-
L) and phased to be manageable for design and construction. The projects were first ranked based on the
inadequacy of the bridge rail and then by the location in which the greatest benefit would be achieved.
Although not specifically identified through the risk-based prioritization scoring, this project is a high priority for Kittitas
County due to the number of locations observed to be at high risk with the potential for high severity accidents
throughout the entire county road system. The potential accidents that this project would prevent are serious injury
and fatal accidents. The County has identified this widespread hazard and is taking a proactive, systemic approach to
reduce the potential for future accidents.
There have been 60 bridges rated as Code 3; this rating reflects bridges with timber railing or no railing at all. Of all
the bridges identified with substandard rail, these bridges or structures have the highest vulnerability because they
provide no protection for an errant vehicle.

o ESTIMATED COST $617,553
• Phase 3 is within County Maintenance Districts J-L with 20 bridges or structures.
o ESTIMATED COST $695,379
• Bridges that have been coded 3
are severely inadequate bridges or
structures with wood rail or no rail
at all.
• There will be three projects by
geographic location of code 3
bridges to allow for manageable
and cost-conscious improvements.

Priority 3: Denmark Road Safety Improvements
Safety countermeasures and roadway improvements of a sharp corner with steep embankments at MP 3.57 would
aid to prevent run-off-road accidents on this specific road as it has a history of accidents at this location and was
identified in previous road safety plans. The priority level is lower than other projects because it only targets a specific
location and road characteristic. The county included multiple road segments to provide improvements to this entire
roadway corridor, from MP 0.50 to MP 4.35 which includes bundling bridge rail improvements to the project for
efficiency and cost-effective contract letting. This segment includes five Code 3 bridges within maintenance district K:
79143-ob, 79144, 79261-ob, 79262-ob, 79351-ob. Recent improvements at this site include extension of the culvert
under Denmark Rd by about 15ft and the addition of rock to prevent undercutting of road. The shoulders of the
roadway were also built up by 2 ft on the outside of the corner and 3 ft on inside of the corner. Further
countermeasures such as those mentioned in this section are needed as this work itself does not prevent run off road
events.

Priority 3: Denmark Rd Safety Improvements
ESTIMATED COST $431,498
• Denmark Rd from MP 0.50 to MP 3.08 has several structures in need of adequate railing.
• Denmark Rd from MP 3.08 to MP 4.35 has steep curves, both vertical and horizontal. The road narrows
greatly at the corner with steep embankments on both sides of the road. The countermeasures in place are
minimal and no rail is present at the corner.
• Recent improvements include extension of the existing culvert and the addition of rock to prevent
undercutting of the roadway and shoulder buildup.
• Denmark Rd includes five bridges rated as Code 3 (see Priority Two in this plan). Bridge IDs are: 79143-ob,
79144, 79261-ob, 79262-ob, 79351-ob.
Priority 4: Bridge Rail Improvements – Code 2
Phase 1- County Maintenance Districts A - D
• 6 bridges or structures
Phase 2- County Maintenance District E
• 16 bridges or structures
Phase 3- County Maintenance District F
• 17 bridges or structures
Phase 4- County Maintenance District G
• 21 bridges or structures
Phase 5- County Maintenance District H - I
• 14 bridges or structures
Phase 6- County Maintenance District J - K
• 14 bridges or structures
Phase 7- County Maintenance District L
• 12 bridges or structures
The second highest risk bridges or structures were rated as Code 2. These bridges have railing that do not meet
WSDOT’s modern standards for crashworthiness and do not have approach railing. Many of these bridges have w-
section metal beam rail and steel posts attached to the outer edge of the bridge deck. This is a design that was crash
tested and approved by FHWA in 1959 and has since been discontinued due to a tendency of the concrete deck to
fail at the post connection upon impact, allowing errant vehicles to continue off the deck. Bridges without approach
railing do not provide any protection to an errant vehicle that leaves the roadway just before the bridges. There are
100 bridges that are coded 2 throughout Kittitas County. As with priority 2, this project will be broken into 7 phases to
create more manageable projects for design and construction.
20
Priority 4: Bridge Rail Improvements
Code 2
• Phase 1 is within County Maintenance Districts A-D with 6 bridges or structures.
o ESTIMATED COST $893,325
• Phase 2 is within County Maintenance District E with 16 bridges or structures.
o ESTIMATED COST $1,085,245
• Phase 3 is within County Maintenance District F with 17 bridges or structures.
o ESTIMATED COST $1,112,359
• Phase 4 is within County Maintenance District G with 21 bridges or structures.
o ESTIMATED COST $1,173,879
• Phase 5 is within County Maintenance Districts H-I with 14 bridges or structures.
o ESTIMATED COST $1,007,091
• Phase 6 is within County Maintenance Districts J-K with 14 bridges or structures.
o ESTIMATED COST $876,199
• Phase 7 is within County Maintenance Districts L with 12 bridges or structures.
o ESTIMATED COST $658,463
• There are 100 bridges that have been coded 2 for inadequate rail with no approaches.
• There will be seven projects by maintenance districts of coded bridges to allow for manageable and cost-
conscious improvements.
Priority 5: Bridge Rail Improvements – Code 1
Phase 1- County Maintenance Districts A-D
• 2 bridges or structures
Phase 2- County Maintenance District E
• 1 bridge or structure
Phase 3- County Maintenance Districts F-L
• 15 bridges or structures
These bridges were identified with lower risk because they feature bridge rail and approaches; however, the rail
and/or approaches and terminal do not meet WSDOT’s current standards for crashworthiness and will need to be
upgraded to maintain adequate protection for errant vehicles. There are 18 bridges and/or structures that have been
rated as Code 1. These structures have rail and approaches yet do not meet code. The priority is low on this project
as the bridges are functional but will need updated railing in the future to assist in preventing serious injury or fatal
accidents.
22
Priority 5: Bridge Rail Improvements
Code 1
• Phase 1 is within County Maintenance Districts A-D with 2 bridges or structures.
o ESTIMATED COST $478,583
• Phase 2 is within County Maintenance District E with 1 bridge or structures.
o ESTIMATED COST $1,063,507
• Phase 3 is within County Maintenance District F-L with 17 bridges or structures.
o ESTIMATED COST $518,192
• These bridges or structures will need upgraded rail and approaches to be brought up to standards to
prevent serious injury or fatality accidents if collision should occur.

Priority 6: Huntzinger Road Safety Improvements
a. Phase 1-MP 2.70 to MP 4.88
b. Phase 2-MP 5.14 to MP 6.99
c. Phase 3-MP 6.99 to MP 10.74
Huntzinger Road has several segments of road that scored high on the risk-based prioritization. Although there is no
significant accident data to reflect the hazards, the characteristics of the road show several areas of curves; both
vertical and horizontal, steep embankments, and no shoulder which are the largest contributing factors to run-off-road
accidents. Guardrail, signing and delineation improvements to this corridor are cost-prohibitive so the county has
prioritized the phases in order of mileposts. This project is a priority for Kittitas County because it prevents the most
common type of accident (run-off-road) and scored high on risk-based prioritization, and because recreation
opportunities and new residence traffic are rapidly increasing along this roadway. It is a lower priority than other
projects because we are already addressed the first roadway segments (MP 0.66 to 2.69) in 2017. Kittitas County
would like to acknowledge a current and continuing monitoring and evaluation stage for safety in this segment of
Huntizinger Rd.
24
Priority 6: Huntzinger Rd. Safety Improvements
• Phase 1 is between MP 2.70 to MP 4.88 has several horizontal curves, steep embankments, and no
shoulder in places with minimal countermeasures in place.
o ESTIMATED COST $778,557
• Phase 2 is between MP 5.14 to MP 6.99 where there are steep embankments, no shoulder in areas and
need of guardrail, signs and/or delineation.
o ESTIMATED COST $366,129
• Phase 3 is between MP 6.99 to MP 10.74 with sharp horizontal curves, vertical curves, steep embankments,
very little to no shoulder and inadequate clear zone.
o ESTIMATED COST $586,638
